Nettarinia di Marico

Cinnyris mariquensis

Il maschio è verde iridescente superiormente con un ventre scuro e bande marroni e bluastre attraverso il petto. La femmina è insignificante, con striature sfocate attraverso le parti inferiori giallo pallido. Trovato in boschi, macchia e savana, inclusa la macchia spinosa semi-desertica. La vocalizzazione più distintiva è una serie energica di note “tyip”. Emette anche un canto acuto e confuso. Molto simile a diverse altre specie di nettarinie ma distinto da dimensioni leggermente maggiori e becco più lungo con una base più spessa.

Areale e habitat

It is found in Angola, Botswana, Burundi, Eritrea, Eswatini, Ethiopia, Kenya, Mozambique, Namibia, Rwanda, Somalia, South Africa, South Sudan, Tanzania, Uganda, Zambia, and Zimbabwe.<p>The African population of Marico sunbird was spotted on various occasions in between July and August 2016 in locations southwest of where its previously believed range ended. These records raised a red flag of a southward range expansion and therefore a more detailed investigation of the range expansion of the species was needed. The range of these birds is expanding into the Northern Cape and Free state provinces in central South Africa.<p>There are several theories as to why these birds are expanding or changing their range. It is believed that drought or floods can cause the species to search for a more favourable environment in the nearby vicinity. Since 2014, a severe drought has ravaged large parts of western and central South Africa, serving as a potential explanation for the southward movements of the Marico sunbird.<p>The current range change map was made by comparing the results of the first and second South African Birds Atlas Project's that were undertaken about 20 years apart.<p>It is interesting that they are expanding into the southwest of Africa with drier spaces and less tress as a woodlands species. This signifies that it is also possible that physiology and behaviour are playing a role in the southwestern migration of the species.
